  • Patent number: 11820914
    Abstract: Embodiments described herein relate generally to systems and methods for creating durable lubricious surfaces (DLS) via interfacial modification. The DLS can be prepared via a combination of a solid, a liquid, and an additive that modifies the interface between the DLS and a contact liquid, resulting in an interfacial layer that acts as a lubricant and/or protective coating between the DLS and the contact liquid. The lubricating effect created between the additive and the contact liquid results in enhanced slipperiness, as well as the protective properties that can help with durability of the DLS.
